Legend of the Seeker Season 2 Episode 5 - "Wizard"

Zedd falls victim to a mysterious spell of forgetfulness cast by Shota from eating a persimmon, his favourite fruit. Confused and frightened, Zedd blasts Richard and Kahlan away, and escapes after it doesn't work on Cara. Shota uses her magic to change Zedd back to when he was younger and convinces him he must replace Richard with a new Seeker to find the Stone of Tears. Shota gives Zedd back his knowledge of magic to take the Sword of Truth and compass from Richard.
